I am staring to write the proposal for Qt6 port. I have some general ideas, 
hope it goes well. The first draft should be "okayish". Is there anything else 
would you like to see in a proposal? Or something I should take care of. Also 
what are your final expectations with the AppImage builder?

Thanks
